CHARLES BARREZ, or rams, FRANCE,

' MACHINE FOR THE AUTOMATIC MANUFACTURE or BLOWN-GLASS ARTICLES.

To all whom it may concern:

Be it known that I, CHARLES BARREZ, a

' citizen of the Republic of France, residing at Paris, France, have. invented certain new and useful Improvements ill-Machines for the Autol'nat c Manufacture of Blown- Glass Articles, of which the following is a specification.

The present invention relates to improvements in mach nes for the automatic manufactureof articles of blown glass, bottles,- etc., andis'ichiefly characterized 1.,by the method of automatic opening and closing of the ring-mold, the workman thus not having toattend'to the manipulation of the mold, which results in the economy of. movements, reliability and rapidity of the manufacture 2; by the easy and adjustable manipulation of the punch intended for closing theringsmold and the admission-or inlet for air, forblowing. 3. by the-very simple method of opening and closing the molds, raising a'nd lowering the bottom and the compressor, these movements being brought about simply bythe manipulation of-a cock for distributing and discharging compressed-air. 4. by the use of a per- 'manent perforating bottom and the rotation of bottleson the machine itself, 5. by the use of various accessory parts, such as a per-- foratedor non-perforated cup with air circulation, the cup being capable of rotating about the blank, coolingdev1ces,extractors of finishedzbottles, all the above parts reducin'gthe movements of the attendant, or

enabling the manufacture .to be otherwise improved or simplified. (3. by the whole of these combinations which make this machine an entirely. new machine in whichthe work of the attendant is reduced to a minimum, thereby making the manufacture more reliable and enabling the output to be increased.

A machine according to this invention is illustrated in the accompanying drawings, in Which: I 1

47 to 55 are various parts of the apparatus serving for removing the'bottles from the machine. Air-inlet pipes connect the cylinders for manipulating the molds and the bottom to the distributing cock, and are arranged as may be thought advisable, or concealed in the frame.

The working of the machine is as follows':--The ring-mold 17 being in its upper position (Fig. 1) the attendant turns the hand-wheel operating the cock 7, and air is admitted against the pistons 12 of the cylinders 3, thus closing the rough-shaping mold 9 by forcing inward the rods 8. At the same time, the two halves of the ringmold 17 are also driven inward b the two semi-circular shoulders 27 on the inner face of the two halves of the rough-shaping mold, and the two molds are thus closed (Fig. 3) without any possibility of accident due to forgetfulness, and by a single operation performed by'the attendant of the machine. The twomold-halves having been closed, the attendant, by means of the handle 28 (Fig. 2) raises the punch 24 arranged in the cylinder 23. The workman attending to the ladling then pours the glass into the roughshaping mold and into the ring-mold 17. A fork, not shown in the drawing, can be provided on the machine for enabling him to support his blowing pipe during the pouring of the glass. The compressor 32 is then operated, if desired, then the attendant releases the handle 28, and the punch 24 is returned to its original positlon by the spring 29.v The descentof the punch is lim ited by the collar 30. At the same t me he turns the hand-wheel 25 in order to allow air to escape from the cylinders 3, and thereby to open ,the .rough-shap1ng mold 9 by means of the springs 13. At the same moment he presses on the pedal 26 and air for blowing the bottle penetrates into the mass of glass through theconduit 31 2) made in the cylinder 23 at the s1de of the 7 punch head 24. The blowing continuing slightly, and the blank bemg released from the rough-shaping mold 9, the attendant turns over the ring-mold and the blank by manipulatin the hand-wheel 14, and the 30 spindle 5 (F1g. 4) the blank supported then by the rin -m0ld coming between the two parts or ha ves of the finishing mold 11. At that moment the attendant, y means of a sprayer 44 45, directs cooling air against 3'5 any portions of the blank whlch'he thinks advisable, at the same tlme shaping the blank with his spoon or cup 39 and cooling it, lengthening or perforating according as may be required by the work and by the object to be attained. The sprayer, in view of its different shapes, could also be used'for cooling different parts of the machine, such as the ring-mold, etc. The blank thus having been brought to the desired state, the @L-:

tendant again turns the hand-wheel 250i. the cock 7, and the air admitted under the piston 15, raises the bottom 6 (Fig. 4), then, by continuing to turn the hand-wheel 25, he

admits air to the istons 12 of the finishing 10o mold and closes t e latter which then surrounds the blank. During all these manipulations the attendant continues to blow the blank, and as soon as the finishing mold is closed and surrounds the blank, he blows 10.5 more energetically, always by means of the pedal 26. When the blowing is completed the attendant opens the finislnng mold 11 by releasing theair behind the piston to allow the spring 13 to, act; the finishing mold, on opening, opensv the ring-mold and -completely releases the bottle whiclr then "rests on the raised bottom 6.,

The opening of they ring-mold by the finishing mold is efi'ected by means of the stops 22 which come into contact with the tappets 21 during the opening movement of the finishing mold, the rods 19 for manipulating the ring-mold sliding them in their supports 17 (Fig. 5)..

As already stated, the bottle is en ported freely on the bottom 6, so that a oy has merely to take it and trans ort it to the anneahng furnace. The atten ant then lowers the bottom 6 by turningthe cock 7 to allow the spring 16 to act; then, by rotating in the opposite direction the hand-wheel 14 of the spindle 5, the open ring-mold is returned into the position shown 1n Fi 1 and the operations hereinbefore describedsame handle,

three-quarters in the center with an opening before described.

can again take place for the manufacture of another bottle' In theevent of its being desired to make a kick in the mold, the following arrangement could be adopted: Instead of the bottom 6, its supporting "rod is PIOVIClQCl WIiZh a special kicl -forming.bot-tom 33 34 (Fag, 6) comprising the bottom proper conslstm'g of a hollow part 34 of refractory clay or other material contained in a cast iron frame 33, the said two parts being providedfor the passage of the recessing device35. This bottom being in place, and the finishing mold closed and containing the blank, the attendant presses on the handle 36, which raises the recessing device 35 through the clay bottom,"and penetrates into the blank, forcing back the glass, and atthe same time he imparts to the bottom, by means of the a turning movement of about of a revolution, thenhereleases the handle 36 whereupon the bottom is recessed and finished and it only remains to open the finishing mold as herein- The recessing device instead of being operated by hand, could also be operated automatically, and the shape of the recessing device and of the clay-bottom can also vary in accordance with the shapes to be obtained. f

v The spoon or cup (Fig. 8) used for supporting and working the blank as hereinbefore described, could in certain cases be provided with perforations in the bottom,

the said perforations dented.

with the shape of the articles to be treated. The bottlehaviug been completed, and

the finishing mold opened, thobottle, in-

stead of being re oved by a'boy as stated, could be withdrawn from the bottom by an automatic bottle extractor shown in the drawings in Figs. 0 and 11 in elevationv and plan. This apparatus comprises an arm 46 secured to the machine and supporting a pipe or tube 47 movable on the said arm, a spring 48, a curved arm 49 secured to the tube and provided at the end with a fork or gripper 50 intended to seize the bottle under the ring. This fork could be provided with an opening and closing mo-' tion for betterseizing and holding the hot- The working of this apparatus is as follows :'Thc bottle having been completed, the attendant opens the vided (when the said apparatus is used) on one of its halves with a stop 51 which, mold, strikes atappet 52 (Fig. 11) which partly rotates the tube and with the prising an upright arm,

finishing mold proat the end of its travel, it meets a pedal or lever 53 which, by raising a rod 54, releases the. whole movable part of the extractor, that is to say, the tube 47, the curved arm 49, the gripper 50 and the bottle supported by it, and the whole, operated by the spring 48, turns, and the bottle is thus automatlcally removed from the bottom without the attendant having to attend to it. It is then removed from the gripper 50 either by striking a stop 55, or by the boy himself.

1 What I claim as my invention and desire to secure by Letters Patent is 1. In a machine for making bottles or other hollow articles of glass the combination with divided rough-shaping and finishing molds, supports therefor, a source of compressed a1r, a palr of opposltely-arranged cylinders adjacent the parts of the roughshaping mold, a pair of oppositely-arranged cylinders adjacent the parts of the finishmg mold, a reciprocable piston in each of the cylinders, rods connected with the pistons arts of the rough-shaping and finishing moles as set forth, a spring within each cylinder arranged to act upon each of the pistons, a regulating cock adapted to regulate'the fiow of the compressed air, and connections between the said cock and the respective cylinders, of a movable divided ring-mold arranged in the path of the closing movement of the parts of the roughshaping moldand adapted to be operated thereby so as to close as described, and means intermediate the ring-mold sections and the parts of the finishing mold whereby said ring mold will be opened by the opening movement of the' parts of the finishing mold.
